I'm working on transcription/aural training etc and using Santana's 'Evil Ways' have got this far:
The main body of the song (ignoring the rest for now) goes back and forth between Gm and Bb and the song resolves to Gm. So, Im thinking the
theoretical scale is F and the chords built from that scale are:
F Gm Am Bb C Dm Edim.
But - as the tonal center seems to be Gm I figure the song is actually in G dorian.
Now the question is this - could the song correctly be called a:
ii-IV progression in F, or a
i - III in Gm, or a
i - III in G dorian?
I'm thinking the most correct answer must be the third one, but I need to know if my logic is correct on this and that the way I've notated the chords is correct - assuming that the possible progressions of the G dorian scale would be:
Gm---Am---Bb---C---Dm---Edim----F
-i-----ii----III---IV---v----vi dim--VII
or am I just getting myself horribly confused??
I'm just working on the body of the song, btw - I know there are other chords in there, but for now I'm just thinking about the first 2.
Thanks!
